“You enjoyed the benefit of Cristal champagne worth £700 a bottle, and Louis Vuitton trainers costing up to £795.

“It's reasonable to assume you were living a millionaire lifestyle, you had that sort of money to spend.

“You were making vast profits from the trading of buying and selling heroin on a commercial scale.”

Davis was caught red-handed dropping off some heroin to Desmangles during a raid on September 28 last year.

Leader of the drugs operation, Warren Desmangles, 31, of Canary Wharf, described it as ‘pretty close to the top of the tree.’

Desmangles was jailed for 16 years in March this year.

The pushers splashed out on a chauffeur-driven Rolls Royce, £21,000 Rolex watches and designer threads from Paris after raking in a fortune running a string of drugs factories.

They also drove supercars including a Lamborghini and amassed an impressive collection of Dom Perignon and Cristal champagne, worth £700 a bottle.

Prosecutor Kerry Broom said the gang brazenly photographed themselves with the 'spoils' of their crimes, posing to show off the soles of their designer shoes and wearing three Rolexes.

After the duo was arrested, new factories were set up in Alexandra Road, Enfield, Durmont Road in Hackney, and Park Cliff Road in Dartford, Kent.

A hoard of paraphernalia was also discovered, including two presses and food processors, together with numerous kilos of cutting agents including caffeine and paracetemol, and money counting machines.

Desmangles' cousin, Darren Husbands, 33, of Buckinghamshire, together with Alistair Odoi, 37, of Stoke Newington, Jason Willis, 25, of Waltham Abbey, Essex and Duane Watson, 30, of Tottenham are due to be sentenced on Friday.

Davis also admitted a further charge of possessing criminal property, as did Odoi, who also pleaded guilty to having a prohibited stun gun.
